Abstract: A compression ignition type engine, wherein a first combustion where the amount of the recirculated exhaust gas supplied to the combustion chamber is larger than the amount of recirculated exhaust gas where the amount of production of soot peaks and almost no soot is produced and a second combustion where the amount of recirculated exhaust gas supplied to the combustion chamber is smaller than the amount of recirculated exhaust gas where the amount of production of soot peaks are selectively switched between. When the first combustion is switched to the second combustion or the second combustion is switched to the first combustion, the amount of fuel injection is reduced and the amount of reduction of the output torque of the engine is compensated for by the output torque of an electric motor.

Abstract: Current aqueous methods for removal of polymeric materials from the sidewalls of trenches etched into silicon wafers by reactive-ion-etching are inadequate for treating deep trenches having high aspect ratios. Spin-dry operations performed after the aqueous etching are incapable of completely removing rinse water and ionic species from these deep trenches, thereby leaving pockets of liquid. Subsequent evaporation of these pockets results in the concentration and eventual precipitation of residual ionic species creating watermarks. A two stage cleaning method is described in which the first stage dissolves the sidewall polymer and the second stage draws ionic species strongly chemisorbed onto the silicon surfaces into solution. A key feature of the method is that the wafer surface is not permitted to dry until after the final rinse.

Abstract: A method for controlling the addition of liquid treatment chemicals by automatic dose control. The calculation of the amount of chemical to be dosed into the system combines signals from a liquid flow meter, an influent chemical concentration analyzer and/or an effluent chemical concentration analyzer. The signals are directed to a computerized chemical dose controller that analyzes and adjusts the data from the signals and generates an output signal that controls the chemical dosing mechanisms. For example, the automatic dose control method encompasses the ability to set maximum positive and negative limits of control action as well as the ability to automatically or manually control the reset period necessary to allow previous changes to propagate through the system and be displayed at the effluent sensor thereby improving the dosing of the chemical during treatment of a liquid, wastewater for example.

Abstract: A flexible tube for lining pipes and ducts as well as a method and an apparatus for manufacturing thereof are suggested. The flexible tube is composed of a coated fabric of high resilient warp threads as well as woof threads having lower elasticity. With the flexible tube thus suggested, strong curvatures or angles being present in the pipes can be lined without wrinkles and all-over for the first time.This is enabled in that the high resilient warp threads are stabilized by covering yarn upon straight pipe portions and hence comprise a limited linear extension such that the flexible tube can be placed inside the pipe in quality.In the curved pipe portions the high elasticity of the basic warp thread is activated by a force increase during passing through these portions by compensating the forces of the covering yarn, such that the flexible tube closely fits to the inner pipe wall, all-over and without any wrinkles in these regions.
